Poliwag's my favourite for sure! It's an adorable Pokémon and I love frogs so there's nothing to dislike here. I can't think of a much cuter Pokémon, especially from the the Water-type list, and it evolves into some incredibly cool stuff. I also voted 'Other' for Relicanth because he's one of my all-time favourite Pokémon - everything about him is just so cool and mysterious haha.
